The more expensive 3D glasses from Samsung we can recommend without restrictions. She sits much better than the TV supplied "cheap" sunglasses and also no longer slip. The charging function via USB port directly on the TV is also awesome. Thus, the change of batteries for the glasses unnecessary. As we direct comparison (2 included, "cheap" and 2 "more expensive" glasses) have, I can look at each wants its Samsung TV 3D movies, only recommend this investment. If I had to ever pull off a star, then only for the proud price. But all in all, we are fully satisfied, deshlab 5 Stars!
